Opensolr Changelog — Recent Updates & Improvements

Facet Mapping Apr 24, 2026

New Every indexable WordPress source is now mappable — core post columns (post_title, post_content, post_excerpt, post_date, post_author, …), ALL postmeta keys (the underscore-prefixed WooCommerce core fields like _price, _sku, _stock, _thumbnail_id are now visible — previously hidden as "private"), every public taxonomy, all WooCommerce pa_* attribute taxonomies, plus synthetic featured_image_url and gallery_image_urls aggregates.

New Opensolr Search Drupal module 3.8.0 tagged on drupal.org — first public release since 3.6.0. Configurable result thumbnail field, auto-suggesting Facet Mapping form, full multi-valued field pipeline (crawler + ingestion + meta tags).

New Opensolr Search WordPress plugin 1.0.19 is live on WordPress.org — admins will see the update prompt within 15 minutes of publication. Major Facet Mapping overhaul, plus every fix from the last two weeks rolled into one stable release.

New Opensolr Search for WordPress 1.0.7 — adds the Lexical Only search mode, matching the Opensolr admin and Drupal module. Explicit opt-out from vector: no embedding API call is made, search runs through the lexical edismax path. The Minimum Relevance Score slider auto-zeroes the moment the radio is picked (backend enforces this on save and at query time as well). Yellow note in Search Mode explains the coupling.

New Opensolr Search for Drupal 3.5.0 — adds the Lexical Only search mode, matching the option in the Opensolr admin. Skips the embedding request entirely and runs pure lexical search. When selected, the Minimum Relevance Score is auto-zeroed (on save and at query time) so results aren't filtered out by a hybrid-calibrated threshold. Same feature across the stack — Opensolr admin, Drupal module, WordPress plugin.

New New Lexical Only search mode in Search Tuning → Search Mode. Explicit opt-out from vector — no embedding API call is made, search runs straight through the lexical edismax path. Useful for deterministic BM25 ranking, avoiding embedding API latency, or users on plans without vector who want explicit control instead of the implicit server-side fallback. When selected, the Minimum Relevance Score slider auto-zeros itself (that threshold is calibrated for the combined hybrid score; a positive value would filter out every result in pure lexical mode) and a yellow note explains the coupling.

New Opensolr Search for WordPress 1.0.5 — adds the Minimum Relevance Score slider to Search Tuning, matching the feature in the Opensolr admin and Drupal module. Drops low-scoring hybrid hits from results and facet counts, cleaning up catalog and content searches. Slider is in 0.1 increments, default 0.3.

New Opensolr Search for Drupal 3.4.0 — adds the Minimum Relevance Score slider to Search Tuning, matching the feature in the Opensolr admin. Drops low-scoring hybrid hits from results and facet counts. Slider is in 0.1 increments, default 0.3. Includes an update hook that restores the setting for sites upgrading from older versions.

New New Search Operators help button next to the Search bar. Opens a panel explaining "phrase match", +required, and -excluded operators with examples and a note on why they matter in hybrid search. Users can now refine queries like +laptop "13 inch" -refurbished and cut through semantic noise instantly.
New New Minimum Relevance Score slider in Search Tuning. Drops hits whose combined lexical + vector score falls below the threshold, cleaning noise out of facet counts and result totals. Essential for hybrid search on catalog-style content — without it, numFound balloons to the entire filter set and facet counts pick up docs the user would never consider relevant. Slider moves in 0.1 increments, default 0.3, 0 disables.

New Export CSV from Query Analytics — every table in the Analytics Dashboard (Popular Queries, Latest Queries, Path Distribution, Queries Over Time, Per-Server Stats) now has a green Export CSV button. Downloads are UTF-8 BOM-encoded for Excel compatibility, and the Latest Queries export respects your active filters (search, HTTP status, IP address).

New Hierarchical drill-down facets — navigate multi-level taxonomies like breadcrumbs (e.g. Products > Electrical testing > Clamp meters). Auto-detected from JSON-LD BreadcrumbList data. Supports starting from any level and "Show more" for large lists.

New Search Facet Filters configuration section in the admin panel — discover all indexed fields via Solr schema, map them as list, slider, or date range widgets, drag to reorder. Embeddable search also supports facets via data-sidebar="on".

New AI and vector features (AI Hints, AI Reader, Vector Embeddings, Hybrid Search) are now gated per package. Indexes without vector access get a friendly upgrade prompt instead of a generic error. Lexical keyword search continues to work on every plan.

New Facet filter sidebar — filter search results by category, price, date, and any structured field. Supports list facets, numeric sliders, and date range pickers. "Show more" dialog with letter index for browsing large facet lists. Active filters shown as removable pills. Configure facets from the admin panel under Search Facet Filters.
